Abstract
Abstract A synthetic resin bottle produced by blow-molding a parison of a synthetic resin. In the blow-molding process of the parison, the portion of the parison supporting the handle is prevented from being expanded, thereby to sufficiently increase the supporting strength of the handle. Since the bottle product has its drum recessed in the vicinity of the handle, the grip of the handle can be facilitated.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
158 words
A synthetic resin bottle having a handle, a bottle body, and a neck, said bottle prepared by biaxially orienting a parison of a synthetic resin by a blow molding process and comprising: a handle connected only to and protruding first laterally and then downwardly of a lower portion of the neck of said bottle and formed integrally with said lower neck portion by injection molding without biaxial orientation; an upper body portion extending downward of said neck and biaxially oriented only in the direction away from said handle; and a lower body portion extending downwardly of said upper body portion and having its handle side biaxially oriented laterally to the lateral extent of the lower free end of said handle, and its side opposite its handle side biaxially oriented laterally to the lateral extent of the lower most part of said upper body portion, said lower body portion being formed with a bottom wall at its lower end.
Claim 2
Dependent Claim
158 words
A synthetic resin bottle having a handle, a bottle body, and a neck, said bottle prepared by biaxially orienting a parison of a synthetic resin by a blow molding process and comprising: a handle connected only to and protruding first laterally and then downwardly of a lower portion of the neck of said bottle and formed integrally with said lower neck portion by injection molding without biaxial orientation; an upper body portion extending downward of said neck and biaxially oriented only in the direction away from said handle; and a lower body portion extending downwardly of said upper body portion and having its handle side biaxially oriented laterally to the lateral extent of the lower free end of said handle, and its side opposite its handle side biaxially oriented laterally to the lateral extent of the lower most part of said upper body portion, said lower body portion being formed with a bottom wall at its lower end.
Claim 3
Dependent Claim
35 words
A synthetic resin bottle with a handle, as set forth in claim 1, further comprising annular ribs formed between said upper and lower body portion and at a lower portion of said lower body portion.
Claim 4
Dependent Claim
211 words
A synthetic resin bottle having a handle, a bottle body, and a neck, said bottle prepared by biaxially orienting a parison of a synthetic resin by a blow molding process and comprising: a handle connected to and protruding first laterally outwardly then downwardly of a lower portion of the neck of said bottle then laterally inwardly to connect to an intermediate point on said bottle body, said handle formed integrally with said lower neck portion and with said body by injection molding without biaxial orientation; an upper body portion extending downwardly of said neck and biaxially oriented only in the direction away from said handle; and a lower body portion extending downwardly of said upper body portion and having its handle side biaxially oriented laterally of the lateral extent of said handle, and its side opposite its handle side biaxially oriented laterally to the lateral extent of the lower most part of said upper body portion, said lower body portion being formed with a bottom wall at its lower end, said intermediate point on said bottle body located at a lower portion of said upper body portion, the handle, including the handle portions connected to said body at said lower neck portion and said intermediate point being free of biaxial expansion.
Claim 5
Dependent Claim
211 words
A synthetic resin bottle having a handle, a bottle body, and a neck, said bottle prepared by biaxially orienting a parison of a synthetic resin by a blow molding process and comprising: a handle connected to and protruding first laterally outwardly then downwardly of a lower portion of the neck of said bottle then laterally inwardly to connect to an intermediate point on said bottle body, said handle formed integrally with said lower neck portion and with said body by injection molding without biaxial orientation; an upper body portion extending downwardly of said neck and biaxially oriented only in the direction away from said handle; and a lower body portion extending downwardly of said upper body portion and having its handle side biaxially oriented laterally of the lateral extent of said handle, and its side opposite its handle side biaxially oriented laterally to the lateral extent of the lower most part of said upper body portion, said lower body portion being formed with a bottom wall at its lower end, said intermediate point on said bottle body located at a lower portion of said upper body portion, the handle, including the handle portions connected to said body at said lower neck portion and said intermediate point being free of biaxial expansion.
